GI Motitility In the Stomach. 1  Two types of movement (motility) occur in the stomach: peristalsis and segmentation (mixing). 2  The contractions occur about every 20 seconds and proceed from the body of the stomach toward the pyloric sphincter. 3  About 20% of the contractions in the stomach are peristaltic waves.
1 As a result of segmentation; a process by which some physical digestion occurs in the small intestine, the chime sloshes back and forth between segments of the small intestine that form when bands of circular muscle briefly contract.2  A helpful animation that outlines the process of peristalsis and segmentation. This image illustrates the segmentation of the chyme that occurs within the small intestine of the digestive tract. 2  Segmentation is the process of mixing the food contents in the digestive tract to create a more uniform mixture throughout.
